Chilled Beam Design Guide - TROX

Specification DID600
drain fittings. Unless otherwise specified, coil
connections shall be bare copper for field
sweating to the water supply circuit. Connections
shall face upwards, be located near the left end
of the beam (when viewing into the primary air
connection
8. (OPTIONAL) The chilled water coil shall be
provided with NPT male threaded fittings where
specified. These fittings must be suitable for field
connection to a similar NPT female flexible hose
spigot and shall be at least 1½” long to facilitate
field connection (by others).
9. Beams shall be delivered clean, flushed and
capped to prevent ingress of dirt.
2.03 Performance
1. All performance shall be in compliance with that
shown on the equipment schedule. Acoustical
testing shall have been performed in accordance
with ISO 3741.
2. Coils shall be rated in accordance with ARI
Standard 410, but their cooling and heating
capacities shall be established in accordance to
European Standard EN15116 for the specific
application on the inlet side of the submitted
chilled beam. Evidence of this testing must be
included in the submittal.
3. Primary airflow rates shall not result in supply
(primary plus induced) airflow rates in excess of
80 CFM per linear foot of (two slot) beam.
4. Chilled water flow rates to the beams shall be
limited to that which results in a maximum ten
(10) foot head loss. Water flow velocities through
the beam shall not exceed 4 FPS.
lowered into the grid module by adjusting the nuts
connecting the threaded rods to the beam.
3. Before connecting the supply water system(s) to
the beams, contractor shall flush the piping
system(s) to assure that all debris and other
matter have been removed.
4. Contractor shall perform connection of beams to
the chilled water circuit by method specified (hard
connection using sweated connection or
connection using flexible hoses.
5. Flexible connector hoses shall be furnished by
others (optionally by the manufacturer). Hoses
shall be twenty four (24) inches in length and
suitable for operation with a bend radius as small
as five (5) inches. Such hoses shall be 100%
tested and certified for no leakage at 500 PSI.
Connector hoses shall consist of a PFTE lined
hose with a wire braided jacket. The hoses shall
be suitable for operation in an environment
between -40 and 200˚F, rated for a least 300 PSI
and tested for leakage at a minimum pressure of
360 PSI. Contractor shall assure that the chilled
water supplying the beams has been properly
treated in accordance to BSRIA publication AG
2/93.
6. No power or direct control connections shall be
required for the operation of the chilled beam.
3.03 Cleaning and Protection
1. Protect units before, during and after installation.
Damaged material due to improper site protection
shall be cause for rejection.
2. Clean equipment, repair damaged finishes as
required to restore beams to as-new appearance.
PART 3- EXECUTION
3.02 Installation
1. Coordinate the size, tagging and capacity of the
beams to their proper location.
2. (RECOMMENDED INSTALLATION
PROCEDURE) Chilled beams up to six feet in
length shall be independently suspended from
the structure above by a four (4) threaded rods of
⅜” diameter (provided by the installing
contractor). For beams beyond six feet in length,
six (6) threaded rods of ⅜” diameter. The upper
end of the rods shall be suspended from strut
channels that are a) mounted perpendicular to
the beam length and b) at least four inches wider
than the beam to facilitate relocation of the
threaded rods along their length. The rods shall
be fixed to factory mounting brackets on the
beam that allow repositioning (at least four
inches) along its length. The beam shall then be
positioned above the acoustical ceiling grid and
